I am rebuilding my Kohler and it has the 2.875 bore. I have not been able to find a complete Stens kit for that bore size. Please let me know if I can get a 2.875 bore kit. The K141 also came in a 2.9375(2 15/16) bore size and kits with piston, rings, rod, gaskets, seals, etc. are available for 100 dollars on ebay. Does anyone know for sure if small and large bore K141 block castings are the same? If so, I will have my machinist bore engine 2.875 (After I get and measure piston) to fit the larger bore kit. Thanks
